| Abstract |
A soft switching interleaved active clamp flyback inverter for a photovoltaic AC module system isproposed. The proposed system includes an interleaved active clamp flyback converter and anunfolding bridge inverter. The interleaved active clamp flyback converter has the advantages of zerovoltage switching (ZVS) performance for the primary switches, reverse-recovery problem alleviationfor the secondary output diodes and small input current ripple. Furthermore, each switch in the flybackconverter operates with a high efficiency point along with an output power using a new optimalcontrol method. Therefore, high efficiency and high power density conversion can be achieved in awith input voltage range by employing the proposed system. In order to verify these, theoreticalanalysis and simulation are performed. |
